NJKO vs. Philadelphia
US Chess League 2008, Round 5

I like this simple move.
6… d5 is considered by theory the more critical move, when White might play 7. exd5 (7. e5!? Ng4 8. Bf4 (8. Bg2!?)
8… g5 9. e6 h5)

10.
White does best to castle on the kingside, since queenside castling has proven a problem in practice: 10. f4 Nd7 11. Be3 Nb6 12.
Stopping Qb6, trading queens and easing Black’s game. But Black has other ways of organizing his forces in this flexible defensive position.
11… Qc8!
A bid for immediate equality, but this may be premature.

An interesting forcing line is 14. e5 Nd7 15. f4 c5!? (15… f6!=) 16. Nxd5 cxd4 17. Nxe7+ Kf8 18. Nxc8 dxe3 19. f5 (19. Rxd7 Rdxc8) 19… Bxa2

17… Qe6!?
A very inter esting solution to Black’s problems and the best way to avoid an isolated pawn at d5 or surrendering the d-file.

White retains a slight structural edge, but it is too little to win with in this position.

b) 6… g6!? seems like a new idea worth noting: 7. Na3 Bg7 8. Nc4
9. exd6 Qxd6 10. Na3 with the id ea of Nc4 seems most appropriate here, taking advantage of the fact that White has not yet played the c4 advance.
9… cxd4 10. exd6 Qxd6 11. Nxd4 Nxd4 12. Bxd4 Rd8
Black has emerged from the opening with a good game and now just needs to activate his Bishops and perhaps exchange White’s better ones.

A fairly equal position, though Black’s pieces are better placed. White might have hopes of making his queenside majority do something.

Black wins a pawn, but it will be hard to make it pay.
31. b4 axb4 32. axb4 Rxb4 33. Ra8+ Kh7 34. Rc8 Nd7 35. Ke4 f5+
Perhaps Black should surrender the c-pawn for the kingside pawns? 35… Rb2!
36. Kd4 Rb6 37. Rc7 c5+ 38. Kc3 Rd6 39. Ng2! g5 40. Ne1 Kg6 41. Nd3
After a great Knight re-routing, White wins back the pawn and gains a passer.

An obvious draw result. Each Rook will be forced to sacrifice itself for the other’s pawn.

Game drawn because neither player has mating material. A classic battle “to the Kings”!

We now have the tabiya of a classic MacCutcheon confrontation. White has good chances on the kingside and Black on the queenside. But White’s superior development allows him to inhibit Black’s queenside play somewhat if he chooses — as Ng does here.
Black also sometimes plays the inferior 10… Qg5+ 11. Qxg5 hxg5 12. g4 (12. f4 gxf4 13. Rf1) 12… f6 13. h4! fxe5 14. dxe5 Nc6 15. Nf3 gxh4 16. Rae1 Psakhis

A concept of Akobian’s, to fix White’s a-pawn on a light square so it can be attacked by the Black Bishop.
